- Enabled compile on Windows (bzip2 library needed).

- Fixed crash after the second call to RsInit::InitRetroShare when keyring does not exist.
The instance of AuthSSL was created twice and AuthGPG was deleted without stopping the thread. Stopped the AuthGPG thread on exit of RetroShare.
- Added the correct path to the keyring for Windows in RsInit::copyGnuPGKeyrings.
- Changed the detection of the portable version on Windows from the file "gpg.exe" to the file "portable".
